    DETAILED DESCRIPTION

    [0052] The disclosure provides chimeric antigen receptors (CARs) and immune cells (e.g. T-cells) comprising CARs (CAR-T cells) that specifically bind to BCMA, and dosing regimens for use in the treatment of MM, including refractory/relapsed MM. The disclosure also provides polynucleotides encoding these CARs, compositions comprising these CAR-T cells, and methods of making and using these CARs and CAR-T cells.

    [0053] The disclosure provides CARs that bind to BCMA (e.g., human BCMA, Uniprot accession number: Q02223-2). BCMA specific CARs provided herein include single chain CARS and multichain CARs. The CARs have the ability to redirect T cell specificity and reactivity toward BCMA in a non-MHC-restricted manner, exploiting the antigen-binding properties of monoclonal antibodies. The non-MHC-restricted antigen recognition gives T cells expressing CARs the ability to recognize an antigen independent of antigen processing, thus bypassing a major mechanism of tumor escape.

    I. BCMA-Specific CARS

    [0054] In some embodiments, CARs provided herein comprise an extracellular ligand-binding domain (e.g., a single chain variable fragment (scFv)), a transmembrane domain, and an intracellular signaling domain. In some embodiments, the extracellular ligand-binding domain, transmembrane domain, and intracellular signaling domain are in one polypeptide, i.e., in a single chain. Multichain CARs and polypeptides are also provided herein. In some embodiments, the multichain CARs comprise: a first polypeptide comprising a transmembrane domain and at least one extracellular ligand-binding domain, and a second polypeptide comprising a transmembrane domain and at least one intracellular signaling domain, wherein the polypeptides assemble together to form a multichain CAR.

    [0055] In some embodiments, a BCMA specific multichain CAR is based on the high affinity receptor for IgE (FcRI). The FcRI expressed on mast cells and basophiles triggers allergic reactions. FcRI is a tetrameric complex composed of a single a subunit, a single subunit, and two disulfide-linked subunits. The a subunit contains the IgE-binding domain. The and subunits contain ITAMs that mediate signal transduction. In some embodiments, the extracellular domain of the FcR chain is deleted and replaced by a BCMA specific extracellular ligand-binding domain. In some embodiments, the multichain BCMA specific CAR comprises an scFv that binds specifically to BCMA, the CD8 hinge, and the ITAM of the FcR chain. In some embodiments, the CAR may or may not comprise the FcR chain. In some embodiments two copies of a rituximab mimotope (e.g., CPYSNPSLC (SEQ ID NO: 397); see also WO 2016/120216, incorporated herein by reference in its entirety) are present. An exemplary construct is show in FIG. 21.

    [0056] As provided herein, the extracellular ligand-binding domain of the BCMA CAR comprises an scFv comprising the light chain variable (VL) region and the heavy chain variable (VH) region of a target antigen specific monoclonal antibody joined by a flexible linker. Single chain variable region fragments are made by linking light and/or heavy chain variable regions by using a short linking peptide (Bird et al., Science 242:423-426, 1988). An example of a linking peptide is the GS linker having the amino acid sequence (GGGGS)3 (SEQ ID NO: 333), which bridges approximately 3.5 nm between the carboxy terminus of one variable region and the amino terminus of the other variable region. Linkers of other sequences have been designed and used (Bird et al., 1988, supra). In general, linkers can be short, flexible polypeptides and preferably comprised of about 20 or fewer amino acid residues. Linkers can in turn be modified for additional functions, such as attachment of drugs or attachment to solid supports. The single chain variants can be produced either recombinantly or synthetically. For synthetic production of scFv, an automated synthesizer can be used. For recombinant production of scFv, a suitable plasmid containing polynucleotide that encodes the scFv can be introduced into a suitable host cell, either eukaryotic, such as yeast, plant, insect or mammalian cells, or prokaryotic, such as E. coli. Polynucleotides encoding the scFv of interest can be made by routine manipulations such as ligation of polynucleotides. The resultant scFv can be isolated using standard protein purification techniques known in the art.

    [0067] The intracellular signaling domain of a CAR according to the disclosure is responsible for intracellular signaling following the binding of extracellular ligand-binding domain to the target resulting in the activation of the immune cell and immune response. The intracellular signaling domain has the ability to activate of at least one of the normal effector functions of the immune cell in which the CAR is expressed. For example, the effector function of a T cell can be a cytolytic activity or helper activity including the secretion of cytokines.

    [0068] In some embodiments, an intracellular signaling domain for use in a CAR can be the cytoplasmic sequences of, for example without limitation, the T cell receptor and co-receptors that act in concert to initiate signal transduction following antigen receptor engagement, as well as any derivative or variant of these sequences and any synthetic sequence that has the same functional capability. Intracellular signaling domains comprise two distinct classes of cytoplasmic signaling sequences: those that initiate antigen-dependent primary activation, and those that act in an antigen-independent manner to provide a secondary or co-stimulatory signal. Primary cytoplasmic signaling sequences can comprise signaling motifs which are known as immunoreceptor tyrosine-based activation motifs of ITAMs. ITAMs are well defined signaling motifs found in the intracytoplasmic tail of a variety of receptors that serve as binding sites for syk/zap70 class tyrosine kinases. Examples of ITAM used in the disclosure can include as non limiting examples those derived from TCR, FcR, FcR, FcR, CD3, CD3, CD3, CD5, CD22, CD79a, CD79b and CD66d. In some embodiments, the intracellular signaling domain of the CAR can comprise the CD3 signaling domain which has amino acid sequence with at least about 70%, preferably at least 80%, more preferably at least 90%, 95%, 97%, or 99% sequence identity with an amino acid sequence shown in SEQ. ID NO: 324. In some embodiments the intracellular signaling domain of the CAR of the disclosure comprises a domain of a co-stimulatory molecule.

    [0069] In some embodiments, the intracellular signaling domain of a CAR of the disclosure comprises a part of co-stimulatory molecule selected from the group consisting of fragment of 41BB (GenBank: AAA53133.) and CD28 (NP_006130.1). In some embodiments, the intracellular signaling domain of the CAR of the disclosure comprises amino acid sequence which comprises at least 70%, preferably at least 80%, more preferably at least 90%, 95%, 97%, or 99% sequence identity with an amino acid sequence shown in SEQ. ID NO: 323 and SEQ. ID NO: 327.

    [0070] CARs are expressed on the surface membrane of the cell. Thus, the CAR can comprise a transmembrane domain. Suitable transmembrane domains for a CAR disclosed herein have the ability to (a) be expressed at the surface of a cell, preferably an immune cell such as, for example without limitation, lymphocyte cells or Natural killer (NK) cells, and (b) interact with the ligand-binding domain and intracellular signaling domain for directing cellular response of immune cell against a predefined target cell. The transmembrane domain can be derived either from a natural or from a synthetic source. The transmembrane domain can be derived from any membrane-bound or transmembrane protein. As non-limiting examples, the transmembrane polypeptide can be a subunit of the T cell receptor such as , , or , polypeptide constituting CD3 complex, IL-2 receptor p55 ( chain), p75 ( chain) or chain, subunit chain of Fc receptors, in particular Fc receptor III or CD proteins. Alternatively, the transmembrane domain can be synthetic and can comprise predominantly hydrophobic residues such as leucine and valine. In some embodiments said transmembrane domain is derived from the human CD8 chain (e.g., NP_001139345.1). The transmembrane domain can further comprise a stalk domain between the extracellular ligand-binding domain and said transmembrane domain. A stalk domain may comprise up to 300 amino acids, preferably 10 to 100 amino acids and most preferably 25 to 50 amino acids. Stalk region may be derived from all or part of naturally occurring molecules, such as from all or part of the extracellular region of CD8, CD4, or CD28, or from all or part of an antibody constant region. Alternatively the stalk domain may be a synthetic sequence that corresponds to a naturally occurring stalk sequence, or may be an entirely synthetic stalk sequence. In some embodiments said stalk domain is a part of human CD8 chain (e.g., NP_001139345.1). In another particular embodiment, said transmembrane and hinge domains comprise a part of human CD8 chain, preferably which comprises at least 70%, preferably at least 80%, more preferably at least 90%, 95% 97%, or 99% sequence identity with amino acid sequence selected from the group consisting of SEQ ID NO: 318. In some embodiments, CARs disclosed herein can comprise an extracellular ligand-binding domain that specifically binds BCMA, CD8 human hinge and transmembrane domains, the CD3 signaling domain, and 4-1BB signaling domain.

Modified cells, which can proliferate independently of the MHC signaling pathway, susceptible to be obtained by this method are encompassed in the scope of the present disclosure. Modified cells disclosed herein can be used in for treating subjects in need thereof against Host versus Graft (HvG) rejection and Graft versus Host Disease (GvHD); therefore in the scope of the present disclosure is a method of treating subjects in need thereof against Host versus Graft (HvG) rejection and Graft versus Host Disease (GvHD) comprising treating said subject by administering to said subject an effective amount of modified cells comprising inactivated TCR and/or TCR genes.

    [0085] In some embodiments, the immune cells are engineered to be resistant to one or more chemotherapy drugs. The chemotherapy drug can be, for example, a purine nucleotide analogue (PNA), thus making the immune cell suitable for cancer treatment combining adoptive immunotherapy and chemotherapy. Exemplary PNAs include, for example, clofarabine, fludarabine, and cytarabine, alone or in combination. PNAs are metabolized by deoxycytidine kinase (dCK) into mono-, di-, and tri-phosphate PNA. Their tri-phosphate forms compete with ATP for DNA synthesis, act as pro-apoptotic agents, and are potent inhibitors of ribonucleotide reductase (RNR), which is involved in trinucleotide production. Provided herein are BCMA specific CAR-T cells comprising an inactivated dCK gene. In some embodiments, the dCK knockout cells are made by transfection of T cells using polynucleotides encoding specific TAL-nuclease directed against dCK genes by, for example, electroporation of mRNA. The dCK knockout BCMA specific CAR-T cells are resistant to PNAs, including for example clorofarabine and/or fludarabine, and maintain T cell cytotoxic activity toward BCMA-expressing cells.

    [0086] In some embodiments, isolated cells or cell lines of the disclosure can comprise a pT or a functional variant thereof. In some embodiments, an isolated cell or cell line can be further genetically modified by inactivating the TCR gene.

    [0087] In some embodiments, the CAR-T cell comprises a polynucleotide encoding a safety switch, such as for example RQR8. See, e.g., WO2013153391A, which is hereby incorporated by reference in its entirety. In CAR-T cells comprising the polynucleotide, the safety switch polypeptide is expressed at the surface of a CAR-T cell. In some embodiments, the safety switch polypeptide comprises the amino acid sequence shown in SEQ ID NO: 342.

    [0088] The safety switch polypeptide may also comprise a signal peptide at the amino terminus. In some embodiments, the safety switch polypeptide comprises the amino acid sequence shown in SEQ ID NO: 400.

    TABLE-US-00006 (SEQIDNO:400) MGTSLLCWMALCLLGADHADACPYSNPSLCSGGGGSELPTQGTFSNVST NVSPAKPTTTACPYSNPSLCSGGGGSPAPRPPTPAPTIASQPLSLRPEA CRPAAGGAVHTRGLDFACDIYIWAPLAGTCGVLLLSLVITLYCNHRNRR RVCKCPRPVV

    [0089] When the safety switch polypeptide is expressed at the surface of a CAR-T cell, binding of rituximab to the R epitopes of the polypeptide causes lysis of the cell. More than one molecule of rituximab may bind per polypeptide expressed at the cell surface. Each R epitope of the polypeptide may bind a separate molecule of rituximab. Deletion of BCMA specific CAR-T cells may occur in vivo, for example by administering rituximab to a subject. The decision to delete the transferred cells may arise from undesirable effects being detected in the subject which are attributable to the transferred cells, such as for example, when unacceptable levels of toxicity are detected.

    [0090] In some embodiments, the CAR-T cell comprises a selected epitope within the scFv having a specificity to be recognized by a specific antibody. See, e.g., PCT application PCT/EP2016/051467, WO2016/120216, mAb-DRIVEN CHIMERIC ANTIGEN RECEPTOR SYSTEMS FOR SORTING/DEPLETING ENGINEERED IMMUNE CELLS, filed on Jan. 25, 2016, which is hereby incorporated by reference in its entirety. Such an epitope facilitates sorting and/or depleting the CAR-T cells. The epitope can be selected from any number of epitopes known in the art. In some embodiments, the epitope can be a target of a monoclonal antibody approved for medical use, such as, for example without limitation, the CD20 epitope recognized by rituximab. In some embodiments, the epitope comprises the amino acid sequence shown in SEQ ID NO: 397.

    [0091] CPYSNPSLC (SEQ ID NO: 397)

    [0092] In some embodiments, the epitope is located within the CAR. For example without limitation, the epitope can be located between the scFv and the hinge of a CAR. In some embodiments, two instances of the same epitope, separate by linkers, may be used in the CAR. For example, the polypeptide comprising the amino acid sequence shown in SEQ ID NO: 398 can be used within a CAR, located between the light chain variable region and the hinge.

    TABLE-US-00007 (SEQIDNO:398) GSGGGGSCPYSNPSLCSGGGGSCPYSNPSLCSGGGGS

    [0093] In some embodiments, the epitope-specific antibody may be conjugated with a cytotoxic drug. It is also possible to promote CDC cytotoxicity by using engineered antibodies on which are grafted component(s) of the complement system. In some embodiments, activation of the CAR-T cells can be modulated by depleting the cells using an antibody which recognizes the epitope.

    [0114] In some embodiments, fludarabine and cyclophosphamide are administered on a first day, and the anti-CD52 antibody (e.g., an antibody comprising the sequence of SEQ ID NO: 408 and/or SEQ ID NO: 410) is administered on a second day. In some embodiments, fludarabine and cyclophosphamide are administered on a first day before administration of the CAR-T cells, and an anti-CD52 antibody (e.g., an antibody comprising the sequence of SEQ ID NO: 408 and/or SEQ ID NO: 410) is administered on a second day; wherein the second day is the same day that CAR-T cells are administered or the second day is after the CAR-T cells are administered. In some embodiments, fludarabine and cyclophosphamide are administered on a first day, CAR-T cells are administered on a second day, and an anti-CD52 antibody (e.g., an antibody comprising the sequence of SEQ ID NO: 408 and/or SEQ ID NO: 410) is administered at least about 1, about 2, about 3, about 4, about 5, about 6, about 7, about 8, about 9, about 10, about 11, or about 12 weeks after the second day. In some embodiments, fludarabine and cyclophosphamide are administered before administration of CAR-T cells, and an anti-CD52 antibody (e.g., an antibody comprising the sequence of SEQ ID NO: 408 and/or SEQ ID NO: 410) is administered at least about 1, about 2, about 3, about 4, about 5, about 6, about 7, about 8, about 9, about 10, about 11, or about 12 weeks after administration of the CAR-T cells.

    [0115] In some embodiments, a lymphodepletion regimen comprises administration of fludarabine and cyclophosphamide (FC). In some embodiments, a lymphodepletion regimen comprises administration of fludarabine and anti-CD52 antibody (e.g., an antibody comprising the sequence of SEQ ID NO: 408 and/or SEQ ID NO: 410) (FA). In some embodiments, a lymphodepletion regimen comprises administration of cyclophosphamide and an anti-CD52 antibody (e.g., an antibody comprising the sequence of SEQ ID NO: 408 and/or SEQ ID NO: 410) (CA).

    [0116] The choice of specific lymphodepletion regimen drugs and dose before a first or second/subsequent dose of CAR-T cells may be determined based on hematological analysis and hematologic recovery of the patient. In the case of redosing, a second lymphodepletion regimen can be more or less intense compared to a first lymphodepletion regimen (for example, based on recovery of lymphocytes, neutrophils, and viral reactivation after a first dose). For example, at the time of redosing, if lymphocyte and neutrophil levels are high, a strong or aggressive lymphodepletion regimen may be used. Alternatively, at the time of redosing, if lymphocyte levels are low, a weaker or less aggressive lymphodepletion regimen may be used. In some embodiments, if the number of blasts at the time of redosing is high, a strong or aggressive lymphodepletion regimen is used. In some embodiments, if the number of blasts at the time of redosing is low, a weaker or less aggressive lymphodepletion regimen is used.

    [0117] In some embodiments, an increased intensity of LD regimen may be applied at the time of redosing (with or without anti-CD52 drug). In some embodiments, a reduced intensity of LD regimen may be applied, for example, in case of grade 3-4 lymphopenia at time of redosing (with or without anti-CD52 drug).

    [0118] In some embodiments, the components of the lymphodepletion regimen of fludarabine/cyclophosphamide (FC) or fludarabine/cyclophosphamide/anti-CD52 antibody (FCA) are administered simultaneously; in other embodiments, the components are administered serially. In some embodiments, the components of the lymphodepletion regimen of fludarabine/cyclophosphamide (FC) or fludarabine/cyclophosphamide/anti-CD52 antibody (FCA) are administered simultaneously on Day 5, Day 4 and Day 3. In some embodiments, the components of the lymphodepletion regimen of fludarabine/cyclophosphamide (FC) are administered prior to the administration of the anti-CD52 antibody. In some embodiments, the fludarabine/cyclophosphamide (FC) are administered on Day 7, Day 6 and Day 5, followed by the administration of the anti-CD52 antibody (A) on Day 4 and Day 3. In some embodiments, the fludarabine/cyclophosphamide (FC) are administered on Day 7, Day 6 and Day 5, followed by the administration of the anti-CD52 antibody (A) on Day 5, Day 4 and Day 3. In some embodiments, the subject receives a FC regimen prior to the first dose of the CAR-T cell therapy; and a FCA regimen prior to a redosing of the CAR-T cell therapy. In some embodiments, the subject receives a FCA regimen prior to the first dose of the CAR-T cell therapy; and a second FCA regimen prior to a redosing of the CAR-T cell therapy.

Indeed, various modifications of the disclosure in addition to those shown and described herein will become apparent to those skilled in the art from the foregoing description and fall within the scope of the appended claims.

    EXAMPLES

    Example 1: Production and Testing of BCMA-1

    [0150] FIGS. 1-16 depict the generation and testing of BCMA-1. BCMA-1 is an allogeneic T-cell containing an integrated self-inactivating third generation, recombinant lentiviral vector that expresses a BCMA CAR. The BCMA CAR comprises a scFv, wherein the scFV of the CAR is P5A2 of Table 1. The scFV comprises a VH and a VL, wherein the VH comprises the amino acid sequence shown in SEQ ID NO: 33 and the VL comprises the amino acid sequence shown in SEQ ID NO: 34 The extracellular region of the CAR also comprises 2 mimotopes that confer recognition by rituximab.

    [0151] The genotype of the BCMA CAR-T-cells is BCMA-CAR.sup.+_TCR.sup._CD52.sup.+/. The cells can be formulated in a solution comprising 5% DMSO. In one embodiment, the cells are formulated as a suspension for infusion in a 1:1 mixture of CryoStor Basal Solution and CryoStor CS10 resulting in a 5% final concentration of dimethyl sulfoxide, and the resulting dosage strength of the formulation is 1410{circumflex over ()}6 BCMA-CAR+_TCR-_CD52+/ T-cells/mL.

    [0152] FIG. 2 shows the rituximab-mediated safety switch enables detection and depletion (with a rituximab antibody) of the BCMA-containing CAR-T cells of the disclosure. BCMA-1 cells were incubated with rabbit complement and rituximab. After 3 hours, cells were stained for CAR expression. The graph sows the percentage of live CAR+ cells (mean+/SEM). (FIG. 2)

    [0153] The cytotoxicity of BCMA-1 was tested against BCMA-expressing cell lines was assessed in vitro by co-culturing BCMA-1 effector cells with target cells stably expressing luciferase at increasing E:T ratios and measuring residual luciferase activity after 24 hours. BCMA-negative REH cells served as a control cell line. Compared to non-transduced control T cells (triangles), BCMA-1 (circles) exhibited dose-dependent cytotoxicity against BCMA-expressing cells but no apparent killing of control cells (REH). The killing activity of BCMA-1 and non-gene-edited BCMA-1 (open circles) was comparable. Graphs represent percentage of cell lysis relative to target cells cultured alone (FIG. 6). Results shown are mean+/SEM of 3 donors. Negative cytotoxicity values (resulting from target cell growth or enhanced luciferase signal during the assay) were plotted as 0% lysis.

    [0154] FIG. 16 shows that the scFV of BCMA-1 does not show off-target binding in tissue cross-reactivity studies, indicating the risk for off-target binding in a clinical setting to be low or non-existent. Testing was done in 13 human tissues. The extracellular domain of the CAR was fused to human IgG2dA D265A (mutation to prevent Fc binding). The method was developed for optimal staining on cell lines overexpressing BCMA. No staining observed in human tissues

    [0155] Result of immunohistochemistry staining in 9 human tissuesa triple signal amplification was carried out to increase signal. There was detection of expected signal in tonsil, lymph nodes, spleen tissues. There was no epithelial binding in breast, pancreas, fallopian tube, prostate, bladder tissues. Accordingly, the risk for unexpected binding is considered low or non-existent.

    TABLE-US-00019 TABLE 8 Dose (10{circumflex over ()}6 viable Dose (10{circumflex over ()}6 viable CAR-T cells) for subject CAR-T cells) for subject Dose Level whose weight 50 kg whose weight <50 kg 1 (starting) 40 20 2 120 80 3 360 240 4 480 360 1 20 7 or 14

    [0168] Dose escalation will generally be governed by the 3+3 design; each dose level can receive cells from at least two different donors; up to five dose levels can be tested. The starting dose is noted as Dose Level 1 in Table 8, in some embodiments, a subject may receive a Dose level of 1 if indicated.

    [0169] Redosing may be carried out, using BCMA CAR-T cells from a different donor, in a relapsed patient, using conditioning with, for example, 20 mg CD52 antibody conditioning.

Induction with or without hematopoietic stem cell transplant and with or without maintenance therapy is considered a single regimen. [0179] b. Received prior proteasome inhibitor, immunomodulatory agent, and an anti-CD38 antibody (unless contraindicated) with at least 2 consecutive cycles of each regimen unless progressive disease was the best response to the regimen. [0180] c. Refractory to the last treatment regimen.

    [0181] 4. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

    [0182] A cycle of treatment is considered as the combination of 1 lymphodepletion and 1 treatment period.

    [0183] One goal of this study is to evaluate the MTD of BCMA-1, and/or establish its RP2D

    [0184] In some embodiments, the study includes 2 parts: dose escalation and dose expansion.

    [0185] In the dose escalation part successive cohorts of patients may receive escalating doses of BCMA-1 in a 3+3 design. At each dose level, the first patient can be treated and observed for 28 days prior to treating subsequent patients with BCMA-1. All patients will generally be monitored closely for dose limiting toxicities (DLTs) during the first 28 days after BCMA-1 infusion. The target DLT rate for BCMA-1 is <33%. An intermediate dose level can be explored between DL1 and DL3 (Table 9). A dosing strategy using 2 different weight bands based on the variations in weight observed in the general population can be implemented. Patients weighing 50 kg can receive a dose 33% to 50% lower than that administered to patients weighing >50 kg. The provisional dose levels in BCMA-1 Escalation in Phase 1, Design B is provided in Table 9. Intermediate Dose level, Dose level 4, and Dose Level 1 can be administered as needed.

    TABLE-US-00020 TABLE 9 Dose (10{circumflex over ()}6 viable Dose (10{circumflex over ()}6 viable CAR-T cells) for subject CAR-T cells) for subject Dose Level whose weight >50 kg whose weight 50 kg 1 (starting) 40 20 2 160 80 3 320 200 Intermediate 240 160 4 480 320 1 20 14

    [0186] Dose escalation will generally be governed by the 3+3 design; each dose level can receive cells from at least two different donors; up to five dose levels can be tested. The starting dose is noted as Dose Level 1 in Table 9, in some embodiments, a subject may receive a Dose level of 1, a Dose level of 4, or an Intermediate Dose level (as displayed in Table 9) if indicated.

    [0187] Accordingly, in Design B, BCMA-1 can be administered on Day 0 by intravenous (IV) infusion for approximately 5 minutes. Escalating doses of 4010{circumflex over ()}6, 16010{circumflex over ()}6, and 32010{circumflex over ()}6 allogeneic CAR T cells can be studied for patients weighing >50 kg. The corresponding doses for patients weighing 50 kg are 2010{circumflex over ()}6, 8010{circumflex over ()}6, and 20010{circumflex over ()}6.

    [0188] An anti-CD52 human IgG1 monoclonal antibody that recognizes the human CD52 antigen and can be used as a part of lymphodepletion regimen.

    [0189] The anti-CD52 antibody can be administered on Day 5, Day 4, and Day 3 by IV infusion over 4 hours at a dose of 13 mg/day concomitantly with fludarabine (30 mg/m2/day) and/or cyclophosphamide (300 mg/m2/day), or the antibody alone. A lower dose at 10 mg/day is planned in case of toxicity. Fludarabine (30 mg/m2/day) can be administered for 3 days.

    [0190] The overall duration of this Phase 1 study is approximately 48 months from first patient enrolled to last patient completed.

    [0191] The dose expansion part can include additional cohorts added to the protocol, to characterize R2PD with the appropriate conditioning regimens of BCMA-1. Up to 3 cohorts of 12 patients in each cohort can be evaluated at the dose levels and conditioning regimens chosen based on the findings from the dose escalation.

    [0192] The study can end when all patients treated with BCMA-1 have been followed for at least 24 months from the initial BCMA-1 infusion, have withdrawn consent for any further contact, been lost to follow-up, or died, unless the study is terminated by the sponsor earlier.

    [0193] Redosing may be carried out, using BCMA CAR-T cells from a different donor, in a relapsed patient, using conditioning with, for example, 20 mg CD52 antibody conditioning.

    Example 4: Phase 2 Study

    [0194] Phase 2 can involve testing an addition cohort of 6-12 subjects using the highest dose with acceptable toxicity from Phase 1 Design A or Design B (either RP2Dthe dose level producing around 20% of dose-limiting toxicity from Phase 1; or the dose level above the RP2D dose). Subjects may receive a CD52 antibody without flu/cy; the CD52 antibody may be administered at a dose of 40 mg (13 mg/day3 days) before the CAR-T cell treatment and repeated at 13 mg/day on Day 7, 14, and 21 after CAR-T cell treatment.
